ADM1041ARQ-2

Overview

The ADM1041ARQ-2 is a secondary-side controller designed for N+1 server power supplies. It provides voltage control, current sharing, and housekeeping functions for single-output configurations. The device integrates a voltage error transconductance amplifier to manage output regulation. It operates within a QSOP-24 package, supporting high-reliability applications in telecommunications and server infrastructure.

Feature Summary

• Provides integrated voltage control and current sharing capabilities for redundant power architectures
• Delivers housekeeping data monitoring for system reliability and diagnostics
• Functions as a secondary-side controller with built-in transconductance amplification

Applications

• N+1 redundant server power supplies
• Telecommunications power systems
• High-reliability single-output power management

Procurement Notes

Verify the specific suffix (e.g., ARQ-2) against the manufacturer's official datasheet to confirm pinout and functional compatibility. Ensure the component matches the required package type and RoHS compliance status. Cross-reference ordering information with authorized distributors to avoid counterfeit parts. Confirm that the selected variant supports the intended N+1 architecture requirements.

Selection Notes

Select this component when designing redundant power systems requiring precise current sharing and housekeeping monitoring. It is suitable for applications needing a dedicated secondary-side controller rather than a primary-side solution. Consider the QSOP-24 package constraints during PCB layout. Evaluate thermal performance and regulatory compliance needs before finalizing the design.

Part Context

This part belongs to Analog Devices' power management portfolio, specifically targeting server and telecom infrastructure. It complements primary-side controllers by managing load balancing and system health. The ADM1041 series is engineered for high-reliability environments where redundancy and accurate current distribution are critical for continuous operation.

Replacement Considerations

Consult official Analog Devices documentation for qualified substitutes. Verify electrical parameters and pin compatibility before swapping components. Generic replacements may lack specific housekeeping or current share features.
